Trial Clinical Study Results:
To evaluate the anti-caries effect of green tea, a group of 150 volunteers were randomly divided into 3 groups: A, B and C with 50 persons in each. People in test groups A and B were given a green tea polyphenol tablet whereas placebo was given to group C (tablets were taken three times daily). After 3 weeks, group A was given placebo and group B continued with polyphenols for 6 weeks. After using polyphenol tablets for 2 weeks, the plaque index of test groups were clearly lower than the control group (P < 0.01). After stopping use of the polyphenol tablet, the effect was still kept for 3 weeks. It can be concluded that polyphenol tablets from Chinese green tea have significant anti-plaque effect and can therefore help to prevent dental cavities.
